“…These cartilages are usually referred to as “post-element” cartilages (e.g. post-hypural cartilages) (Fujita, 1989) because they appear to be prolongations of the hypaxial elements they detach from during the fragmentation of the two plates of connective tissue. Concomitantly, the condensation of chondrocytes intercalated between distal epiphyses of the hypurals or haemal spines associated with the plates of connective tissue led to the formation of a second type of smaller distal caudal radials.…”

“…Concomitantly, the condensation of chondrocytes intercalated between distal epiphyses of the hypurals or haemal spines associated with the plates of connective tissue led to the formation of a second type of smaller distal caudal radials. These cartilaginous elements, associated with the fragmentation of the plate of connective tissue, were previously called “intercalary cartilages” (Cope, 1890) or “accessory cartilages” (Rosen, 1973) or “inter-[element] distal cartilages” (Fujita, 1989) in various teleosts. Because they consistently localized between adjacent hypaxial caudal fin skeletal elements in our gar, we propose to call these radials “intercalated distal caudal radials”.…”

“…The main distal radials in the spotted gar caudal fin skeleton seemed to form by the separation of the cartilaginous tips of the distal epiphyses of hypaxial elements within the plates of connective tissue, and to remain aligned with the hypural or haemal spine they detached from, as in many teleosts, including basally diverging teleosts (Hiodon, Albula, Elops) (Schultze and Arratia, 1988), salmonids (Arratia and Schultze, 1992), and other teleosts (Schultze and Arratia, 1989). These cartilages are usually referred to as "post-element" cartilages (e.g., post-hypural cartilages) (Fujita, 1989) because they appear to be prolongations of the hypaxial elements they detach from during the fragmentation of the two plates of connective tissue.

“…Fusion at their first appearance has never been known to occur between hypural 2 and 3 or any other hypurals. The position of the diastema. In teleosts with a more primitive organization of the caudal fin elements (Figs 1 and 2; Monod 1968; Fujita 1989), the diastema is always located between hypurals 2 and 3. The size of the hypurals. In taxa with a reduced number of hypurals, the remaining hypurals are usually larger, and that can be interpreted as the result of a fusion of individual hypurals to a compound element.…”

Konstantinidis P. and Johnson, G. D. 2012. A comparative ontogenetic study of the tetraodontiform caudal complex. -Acta Zoologica (Stockholm) 93: 98-114.Interpretation of the caudal complex of adult Tetraodontiformes has proven problematic because of the consolidation of the component elements. Here, we show that an ontogenetic approach offers considerable elucidation of the homology of the caudal complex, resulting in a new understanding of the grundplan of these fishes. The reductions of structures of the caudal complex are interpreted in a phylogenetic context. The caudal skeleton of larval triacanthodids resembles that of many adult percomorphs; however, during subsequent development epural 3 disappears, while epural 2 is reduced so that it can hardly be distinguished from the uroneural remnants. Juvenile triacanthids have an epural 2 that is lost in ontogeny, and the cartilaginous parhypural becomes integrated into the large hypural plate. In ostraciids and diodontids, the parhypural is absent throughout development. The hypural plates of adult balistids, monacanthids and tetraodontids have a conspicuous diastema between the dorsal and ventral portions. However, in early stages of the former two, the dorsal and ventral portions are continuous in cartilage proximally and remain fused in the adults. In tetraodontids, the two hypurals are separate from their initial appearance in cartilage and never fuse, raising the question of homology of the individual hypurals among the different families.

Kubicek, K. and Conway, K. W. 2016. Developmental osteology of Sciaenops ocellatus and Cynoscion nebulosus (Teleostei: Sciaenidae), economically important sciaenids from the western Atlantic. -Acta Zoologica (Stockholm) 97: 267-301.The adult skeleton in members of the economically important Sciaenidae is well documented, but information on earlier developmental stages is sparse and often focused on a particular character complex. To generate information on skeletal development in sciaenid fishes, we investigated the ontogeny of the entire skeleton in the western Atlantic Sciaenops ocellatus (Red drum) and Cynoscion nebulosus (Spotted seatrout), which are the focus of successful captive rearing programmes within the southern United States. Development of the skeleton (excluding the basisphenoid and sclerotic bones) is complete in S. ocellatus and C. nebulosus at 14.4 mm SL and 13.5 mm SL, respectively. The basisphenoid did not appear until later in development (21.9 mm SL in S. ocellatus and 19.5 mm SL in C. nebulosus), while the sclerotic bones are not present in the material examined. No major differences are identified between the ossification sequences compiled for each species. Cynoscion nebulosus exhibited variation in the presence/absence of two elements, supraneural 1 and the coronomeckelian. Lastly, we compile and compare available information on skeletal development across members of the Sciaenidae and compare the sequence of ossification compiled for S. ocellatus to that available for Danio rerio and Salminus brasiliensis (entire skeleton), and Chanos chanos (cranium only).Acta Zoologica (Stockholm) 97: 267-301 (July 2016)Kubicek and Conway Skeletal ontogeny of Sciaenops and Cynoscion
